The data below represent commute times (in minutes) and scores on a well-being survey. Complete parts (a) through (d) below. Commute Time (minutes), x Well-Being Index Score, y 15 25 40 60 105 D 69.1 68.1 67.2 66.3 65.1 64.4 62.5 84 O D. For every unit increase in index score, the commute time falls by . on average. (Round to three decimal places as needed.) O E. It is not appropriate to interpret the y-intercept because a commute time of zero minutes does not make sense and the value of zero minutes is much smaller than those observed in the data set. (c) Predict the well-being index of a person whose commute time is 30 minutes. The predicted index score is (Round to one decimal place as needed.) (d) Suppose Barbara has a 20-minute commute and scores 66.9 on the survey, Is Barbara more "well-off" than the typical individual who has a 20-minute commute? Select the correct choice below and fill in the answer box to complete your choice. (Round to one decimal place as needed.) O A. No, Barbara is less well-off because the typical individual who has a 20-minute commute scores O B. Yes, Barbara is more well-off because the typical individual who has a 20-minute commute scores
